Best Christmas Fish Tank Decorations

Decorations belong in an aquarium just as much as fish and plants. Animals need not only food but also a suitable living environment. In addition to the visual aspect, the focus is also on the functional aspect. Animals need retreats where they can sleep and rest. Ideally, you will find decorations that visually fit into the picture and provide added value for the fish.

Especially at Christmas, we decorate our homes and everywhere. It glitters in different colors. But why should you leave out the aquarium? In this article, we show you how you can also create a Christmas landscape in your aquarium. Unfortunately, there are not many suitable decorations available at the moment. If more decorations appear later, we will present them below.

The Best Christmas Fish Tank Decorations

1st Officially Licensed Disney’s Frozen Sliding Olaf


  • Dimensions: 1.25 x 3 x 3.8 inches
  • Weight: 1.13 ounces
  • Material: Resin

Suitable for the Christmas season is the Disney series Frozen. There are small officially licensed figures from the series, which reflect the theme of Christmas very well. This includes, for one, Olaf, the snowman. Especially for children, the use of popular figures can significantly increase the pleasure of the aquarium. Little Olaf lies here on his stomach and slides on the snow. The level of detail is very good, and you can see all the special features.

The figure has a size of 1.25 x 3 x 3.8 inches and a weight of 1.13 ounces. This makes it quite small and therefore well suited for a small aquarium. The use of resin makes it compatible with both saltwater and freshwater tanks. For the fish, the model does not offer any added value, but it can still significantly enhance your aquarium’s look. By purchasing additional decorations from the series, a complete scene can be displayed in which the figures fit together optimally in size.

2nd Christmas Tree Resin Decor


  • Dimensions: 2.95 x 1.77 x 1.77 inches
  • Weight: 1.73 ounces
  • Material: Resin

There is probably nothing more appropriate for Christmas than a Christmas tree. This model made of resin is also suitable for an aquarium. With a 2.95 x 1.77 x 1.77 inches size, the decoration is suitable for a small fish tank. Matching the Christmas tree, you can place gifts around it. How to make them yourself, we will show you at the bottom of the page.

The level of detail of the model is convincing. You can see the lights and the bow on the pot. To prevent the tree from falling over in the aquarium, it should be fixed in the gravel. Larger fish could otherwise knock the tree over. Before putting it in the aquarium, we recommend washing the decoration underwater. Although the resin model is suitable for salt and freshwater tanks, you should remove impurities beforehand to protect the fish.

Finally, we would like to introduce you to a creative way how you can easily make small decorations yourself. Under a Christmas tree belong, of course, gifts, which we want to tinker in this example. For this, you only need pebbles and some ribbon. With the gift ribbon, you tie a bow around the stones. It is best to use different colors. Around a decorative Christmas tree or another plant placed thus comes directly Christmas mood.
